I am currently using FCPx to render a MOV file. Is it possible to convert the file to a format required by a broadcast station - MXF OP1a? I have AME 5.5.0.212 64-bit (Mac based). I can't see any options to export to this setting, though it seems to be supoorted in AME's features.

Any clarification or advice appreciated! I am considering moving over to Adobe Premier CS5.5 if it makes a difference and improves editing speed.

Support for exporting to MXF OP1a was added in the 5.0.1update. However, this format as well as several others are available only if AME was installed by Premiere Pro, After Effects, Production Premium, or Master Collection.
